How do I change the player's force powers in SP in a custom mod and map?

I tried to use the set command in BehavEd, but it seems impossible to add any kind of force powers, because all force powers are immediately set to 0 when I start my mod via .bat. My failed attempts used the "SET_FORCE_[forcepower]_LEVEL" parameter.

- name it (for example level_start)
- compile it and put in script folder (for example new_scripts)
- put all new files into .pk3 (of course new map must be in maps folder in that pack and new_scripts folder must be in scripts folder (as in assets packs)) and put a new .pk3 into "base" directory
- to run my map I use command devmap or change newgame.ui (and newgame_first.ui) to run my map when start a new game...
And it always works fine. So I don't know, may be there is some problem in your .bat file?
P.S. Sorry for my English...
